Quick summary: A clear APP fraud evidence pack helps show what happened before each payment, what the bank knew, and why the refund decision may need review.
Build the payment timeline first
List each payment date, amount, payee name, account details used, payment method and what the scammer told you at that point. The timeline should show the pressure, trust-building and warning signs in sequence.
Keep scammer communications
Messages, emails, adverts, social media profiles, website links, investment dashboards, crypto wallet screenshots and phone logs can help explain why the payment appeared genuine at the time.
Keep bank warnings and bank responses
Where possible, save screenshots or wording of any payment warnings, fraud team messages, branch notes, online banking prompts and final decision letters.
Useful evidence checklist
- Bank statements showing the disputed payments
- Scammer messages, calls, emails and account details
- Bank warning screenshots or notes of what appeared
- Complaint submission and final bank response
- Police report, Action Fraud reference or platform reports if available
- Any evidence of vulnerability, pressure, urgency or impersonation
Quaerens can organise the evidence. If specialist or regulated support may be required, we explain this clearly before any next step is taken.

Practical answer and next steps
Short answer: Report the scam to the bank immediately and preserve the payment trail, messages, warnings and report reference. Different reimbursement rules can apply according to the payment date and payment system.
Key evidence
- Statements and payment confirmations
- Messages, adverts, telephone numbers and URLs
- Bank warnings and fraud-report records
- Report Fraud or police reference if available
First steps
- Save the original documents and dated screenshots.
- Build one chronology of events, payments and replies.
- State the specific correction, refund or remedy requested.
If the complaint is rejected or ignored
Ask the bank for its written reimbursement decision. For eligible Faster Payments or CHAPS APP scam payments made on or after 7 October 2024, the PSR protections usually require prompt handling; disputed bank outcomes can go to the Financial Ombudsman Service.
